Climate change information in Taiwan is summarized according
to the "Climate Change in Taiwan 2017: Scientific Report -
The Physical Science Basis", published by the Ministry of
Science and Technology.
Surface temperature in Taiwan has been increasing for 100
Compared with the average temperature during 1986-2005,
the temperature in Taiwan at the end of 21st century
(2081-2100) in RCP4.5 and RCP8.5 scenarios may increase by
1.3°C to 1.8°C or 3.0°C to 3.6°C respectively.
Record from in Taiwan 1900 to 2017
The Representative Concentration Pathways (RCPs), which
are used for making projections based on these factors,
describe four different 21st- century pathways of GHG
emissions and atmospheric concentrations, air pollutant
emissions, and land use.
∙ RCP4.5: One
intermediate stabilization pathway in which radiative
forcing is stabilized at approximately 4.5 W/m2 after
∙ RCP8.5: One high
pathway for which radiative forcing reaches >8.5 W/m2 by
2100 and continues to rise for some amount of time.

Seasons in Taiwan have changed significantly.
According to statistics from 1957 to 2006, summer in
Taiwan has increased by 27.8 days, but winter has
decreased by 29.7 days. It shows that summer has become
longer and winter has become shorter.
Sea level in Taiwan has been rising in the past few
From 1961 to 2003, the sea level in Taiwan has risen by
an average of 2.4 mm per year, and from 1994 to 2013, has
risen by an average of 3.4 mm per year.
The dry and wet seasons have become more distinct.
The number of extremely heavy rain days has increased
slightly, yet the change in total rainfall has not been
obvious. And the number of light rain days has decreased

Extreme Weather Events
Increased frequency of extreme high temperatures in
According to the data from 1911 to 2017, as the average
temperature in Taiwan has risen, the number of warm days
has increased yet the number of cold days has
The number of extreme rainfall days has increased
The increase of both heavy rain days and no rain days
indicates the probability of increasing flood or drought
in the future.
The proportion of severe typhoons increases
The proportion of severe typhoons and the intensity of
average rainfall has increased due to increasing sea
